The PortKey that allowing one to go through the Ministry’s Wards, needs to be alowed for OUTGOING Only, thus if there is a fight the group holding the PortKey can hoplefuly excap harm.
Good point, Robert.
I had intended for Augusta to keep the portkey under wraps at all times, as it's intended to protect her from attack. Also, they arranged for the new rule to be a temporary measure only.
The downside of having an escape handy is that it can accommodate only a limited number of people at a time.
What about those left behind?
